f9c28222c8 ath79: add support for Senao Engenius ESR1200
FCC ID: A8J-ESR900

Engenius ESR1200 is an indoor wireless router with
a gigabit ethernet switch, dual-band wireless,
internal antenna plates, and a USB 2.0 port

**Specification:**

  - QCA9557 SOC		2.4 GHz, 2x2
  - QCA9882 WLAN	PCIe mini card, 5 GHz, 2x2
  - QCA8337N SW		4 ports LAN, 1 port WAN
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM
  - UART at J1		populated, RX grounded
  - 6 internal antenna plates (omni-directional)
  - 5 LEDs, 1 button (power, 2G, 5G, WAN, WPS) (reset)

**MAC addresses:**

  Base MAC address labeled as "MAC ADDRESS"
  MAC "wanaddr" is not similar to "ethaddr"

  eth0 *:c8 MAC u-boot-env ethaddr
  phy0 *:c8 MAC u-boot-env ethaddr
  phy1 *:c9 --- u-boot-env ethaddr +1
  WAN  *:66:44  u-boot-env wanaddr

**Serial Access:**

  RX on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin

**Installation:**

  Method 1: Firmware upgrade page

    OEM webpage at 192.168.0.1
    username and password "admin"
    Navigate to Settings (gear icon) --> Tools --> Firmware
    select the factory.bin image
    confirm and wait 3 minutes

  Method 2: TFTP recovery

    Follow TFTP instructions using initramfs.bin
    use sysupgrade.bin to flash using openwrt web interface

**Return to OEM:**

  MTD partitions should be backed up before flashing
  using TFTP to boot openwrt without overwriting flash

  Alternatively, it is possible to edit OEM firmware images
  to flash MTD partitions in openwrt to restore OEM firmware
  by removing the OEM header and writing the rest to "firmware"

**TFTP recovery:**

  Requires serial console, reset button does nothing at boot

  rename initramfs.bin to 'uImageESR1200'
  make available on TFTP server at 192.168.99.8
  power board, interrupt boot by pressing '4' rapidly
  execute tftpboot and bootm

**Note on ETH switch registers**

  Registers must be written to the ethernet switch
  in order to set up the switch's MAC interface.
  U-boot can write the registers on it's own
  which is needed, for example, in a TFTP transfer.

  The register bits from OEM for the QCA8337 switch
  can be read from interrupted boot (tftpboot, bootm)
  by adding print lines in the switch driver ar8327.c
  before 'qca,ar8327-initvals' is parsed from DTS and written.
  for example:

    pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));

Driver for both soc (2.4GHz Wifi) and pci (5 GHz) now pull the calibration
data from the nvmem subsystem.

This allows us to move the userspace caldata extraction for the pci-e ath9k
supported wifi into the device-tree definition of the device.

Currently, "mac-address-ascii" cells only works for ethernet and wmac devices,
so PCI ath9k device uses the old method to calibrate.

52992efc34 ath79: add support for Senao Engenius EWS660AP
FCC ID: A8J-EWS660AP

Engenius EWS660AP is an outdoor wireless access point with
2 gigabit ethernet ports, dual-band wireless,
internal antenna plates, and 802.3at PoE+

**Specification:**

  - QCA9558 SOC		2.4 GHz, 3x3
  - QCA9880 WLAN	mini PCIe card, 5 GHz, 3x3, 26dBm
  - AR8035-A PHY	RGMII GbE with PoE+ IN
  - AR8033 PHY		SGMII GbE with PoE+ OUT
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM
  - UART at J1		populated, RX grounded
  - 6 internal antenna plates (5 dbi, omni-directional)
  - 5 LEDs, 1 button (power, eth0, eth1, 2G, 5G) (reset)

**MAC addresses:**

  Base MAC addressed labeled as "MAC"
  Only one Vendor MAC address in flash

  eth0 *:d4 MAC art 0x0
  eth1 *:d5 --- art 0x0 +1
  phy1 *:d6 --- art 0x0 +2
  phy0 *:d7 --- art 0x0 +3

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin

**Installation:**

  2 ways to flash factory.bin from OEM:

  Method 1: Firmware upgrade page:

    OEM webpage at 192.168.1.1
    username and password "admin"
    Navigate to "Firmware Upgrade" page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    "192.168.1.1/index.htm"
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  If you have a serial cable, see Serial Failsafe instructions
  otherwise, uboot-env can be used to make uboot load the failsafe image

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs.bin to '0101A8C0.img'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot
  execute tftpboot and bootm 0x81000000

**Format of OEM firmware image:**

  The OEM software of EWS660AP is a heavily modified version
  of Openwrt Kamikaze. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-ar71xx-generic-ews660ap-uImage-lzma.bin
    openwrt-ar71xx-generic-ews660ap-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  Newer EnGenius software requires more checks but their script
  includes a way to skip them, otherwise the tar must include
  a text file with the version and md5sums in a deprecated format.

  The OEM upgrade script is at /etc/fwupgrade.sh.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied
  at the PHY side, using the at803x driver `phy-mode`.
  Therefore the PLL registers for GMAC0
  do not need the bits for delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

e085812a7d ath79: add support for Fortinet FAP-221-B
FCC ID: U2M-CAP4100AG

Fortinet FAP-221-B is an indoor access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

Hardware and board design from Senao

**Specification:**

 - AR9344 SOC		2G 2x2, 5G 2x2, 25 MHz CLK
 - AR9382 WLAN		2G 2x2 PCIe, 40 MHz CLK
 - AR8035-A PHY		RGMII, PoE+ IN, 25 MHz CLK
 - 16 MB FLASH		MX25L12845EMI-10G
 - 2x 32 MB RAM		W9725G6JB-25
 - UART at J11		populated, 9600 baud
 - 6 LEDs, 1 button	power, ethernet, wlan, reset

  Note:	ethernet LEDs are not enabled
	because a new netifd hotplug is required
	in order to operate like OEM.
	Board has 1 amber and 1 green
	for each of the 3 case viewports.

**MAC addresses:**

1 MAC Address in flash at end of uboot
ASCII encoded, no delimiters
Labeled as "MAC Address" on case
OEM firmware sets offsets 1 and 8 for wlan

  eth0 *:1e	uboot 0x3ff80
  phy0 *:1f	uboot 0x3ff80 +1
  phy1 *:26	uboot 0x3ff80 +8

**Serial Access:**

Pinout: (arrow) VCC GND RX TX

Pins are populated with a header and traces not blocked.
Bootloader is set to 9600 baud, 8 data, 1 stop.

**Console Access:**

Bootloader:

Interrupt boot with Ctrl+C
Press "k" and enter password "1"
OR
Hold reset button for 5 sec during power on
Interrupt the TFTP transfer with Ctrl+C

to print commands available, enter "help"

OEM:

default username is "admin", password blank
telnet is available at default address 192.168.1.2
serial is available with baud 9600

to print commands available, enter "help"
or tab-tab (busybox list of commands)

**Installation:**

Use factory.bin with OEM upgrade procedures
OR
Use initramfs.bin with uboot TFTP commands.
Then perform a sysupgrade with sysupgrade.bin

**TFTP Recovery:**

Using serial console, load initramfs.bin using TFTP
to boot openwrt without touching the flash.
TFTP is not reliable due to bugged bootloader,
set MTU to 600 and try many times.
If your TFTP server supports setting block size,
higher block size is better.
Splitting the file into 1 MB parts may be necessary

example:

$ tftpboot 0x80100000 image1.bin
$ tftpboot 0x80200000 image2.bin
$ tftpboot 0x80300000 image3.bin
$ tftpboot 0x80400000 image4.bin
$ tftpboot 0x80500000 image5.bin
$ tftpboot 0x80600000 image6.bin
$ bootm 0x80100000

**Return to OEM:**

The best way to return to OEM firmware
is to have a copy of the MTD partitions
before flashing Openwrt.

Backup copies should be made of partitions
"fwconcat0", "loader", and "fwconcat1"
which together is the same flash range
as OEM's "rootfs" and "uimage"
by loading an initramfs.bin
and using LuCI to download the mtdblocks.

It is also possible to extract from the
OEM firmware upgrade image by splitting it up
in parts of lengths that correspond
to the partitions in openwrt
and write them to flash,
after gzip decompression.

After writing to the firmware partitions,
erase the "reserved" partition and reboot.

**OEM firmware image format:**

Images from Fortinet for this device
ending with the suffix .out
are actually a .gz file

The gzip metadata stores the original filename
before compression, which is a special string
used to verify the image during OEM upgrade.

After gzip decompression, the resulting file
is an exact copy of the MTD partitions
"rootfs" and "uimage" combined in the same order and size
that they appear in /proc/mtd and as they are on flash.

OEM upgrade is performed by a customized busybox
with the command "upgrade".
Another binary, "restore"
is a wrapper for busybox's "tftp" and "upgrade".

d9566d059c ath79: add support for KuWFi C910
KuWFi C910 is an 802.11n (300N) indoor router with LTE support.

I can't find anywhere the OEM firmware. So if you want to restore the
original firmware you must do a dump before the OpenWrt flash.

According to the U-Boot, the board name is Iyunlink MINI_V2.

Hardware
--------
SoC:   Qualcomm QCA9533 650/400/200/25/25 MHz (CPU/RAM/AHB/SPI/REF)
RAM:   128 MB DDR2 16-bit CL3-4-4-10 (Nanya NT5TU64M16HG-AC)
FLASH: 16 MB Winbond W25Q128
ETH:
  - 2x 100M LAN (QCA9533 internal AR8229 switch, eth0)
  - 1x 100M WAN (QCA9533 internal PHY, eth1)
WIFI:
  - 2.4GHz: 1x QCA9533 2T2R (b/g/n)
  - 2 external non detachable antennas (near the power barrel side)
LTE:
  - Quectel EC200T-EU (or -CN or -AU depending on markets)
  - 2 external non detachable antennas (near the sim slot side)
BTN:
  - 1x Reset button
LEDS:
  - 5x White leds (Power, Wifi, Wan, Lan1, Lan2)
  - 1x RGB led (Internet)
UART: 115200-8-N-1 (Starting from lan ports in order: GND, RX, TX, VCC)

Everything works correctly.

MAC Addresses
-------------
LAN XX:XX:XX:XX:XX:48 (art@0x1002)
WAN XX:XX:XX:XX:XX:49 (art@0x1002 + 1)
WIFI XX:XX:XX:XX:XX:48

LABEL XX:XX:XX:XX:XX:48

Installation
------------
Turn the router on while pressing the reset button for 4 seconds.
You can simply count the flashes of the first lan led. (See notes)
If done correctly you should see the first lan led glowing slowly and
you should be able to enter the U-Boot web interface.

Click on the second tab ("固件") and select the -factory.bin firmware
then click "Update firmware".

A screen "Update in progress" should appear.

After few minutes the flash should be completed.

This procedure can be used also to recover the router in case of soft
brick.

Backup the original firmware
----------------------------
The following steps are intended for a linux pc. However using the
right software this guide should also work for Windows and MacOS.

1) Install a tftp server on your pc. For example tftpd-hpa.

2) Create two empty files in your tftp folder called:
	kuwfi_c910_all_nor.bin
	kuwfi_c910_firmware_only.bin

3) Give global write permissions to these files:
	chmod 666 kuwfi_c910_all_nor.bin
	chmod 666 kuwfi_c910_firmware_only.bin

4) Start a netcat session on your pc with this command:
	nc -u -p 6666 192.168.1.1 6666

5) Set the static address on your pc: 192.168.1.2. Connect the router
	to your pc.

6) Turn the router on while pressing the reset button for 8-9 seconds.
	You can simply count the flashes of the first lan led. If you
	press the reset button for too many seconds it will continue
	the normal boot, so you have to restart the router. (See notes)

7) If done correctly you should see the U-Boot network console and you
	should see the following lines on the netcat session:
Version and build date:
  U-Boot 1.1.4-55f1bca8-dirty, 2020-05-07

Modification by:
  Piotr Dymacz <piotr@dymacz.pl>
  https://github.com/pepe2k/u-boot_mod

u-boot>

8) Start the transfer of the whole NOR:
	tftpput 0x9f000000 0x1000000 kuwfi_c910_all_nor.bin

9) The router should start the transfer and it should end with a
	message like this (pay attention to the bytes transferred):
TFTP transfer complete!

Bytes transferred: 16777216 (0x1000000)

10) Repeat the same transfer for the firmware:
	tftpput 0x9f050000 0xfa0000 kuwfi_c910_firmware_only.bin

11) The router should start the transfer and it should end with a
	message like this (pay attention to the bytes transferred):
TFTP transfer complete!

Bytes transferred: 16384000 (0xfa0000)

12) Now you have the backup for the whole nor and for the firmware
	partition. If you want to restore the OEM firmware from OpenWrt
	you have to flash the kuwfi_c910_firmware_only.bin from the
	U-Boot web interface.

	WARNING: Don't use the kuwfi_c910_all_nor.bin file. This file
	is only useful if you manage to	hard brick the router or you
	damage the art partition (ask on the forum)

Notes
-----
This router (or at least my unit) has the pepe2k's U-Boot. It's a
modded U-Boot version with a lot of cool features. You can read more
here: https://github.com/pepe2k/u-boot_mod

With this version of U-Boot, pushing the reset button while turning on
the router starts different tools:
 - 3-5 seconds: U-Boot web interface that can be used to replace the
 	firmware, the art or the U-Boot itself
 - 5-7 seconds: U-Boot uart console
 - 7-10 seconds: U-Boot network console
 - 11+ seconds: Normal boot

The LTE modem can be used in cdc_ether (ECM) or RNDIS mode.
The default mode is ECM and in this commit only the ECM software is
included. In order to set RNDIS mode you must use this AT command:
	AT+QCFG="usbnet",3
In order to use again the ECM mode you must use this AT command:
	AT+QCFG="usbnet",1

Look for "Quectel_EC200T_Linux_USB_Driver_User_Guide_V1.0.pdf" for
other AT commands

6de9287abd ath79: add support for Senao Engenius EAP1750H
FCC ID: A8J-EAP1750H

Engenius EAP1750H is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

**Specification:**

  - QCA9558 SOC
  - QCA9880 WLAN	PCI card, 5 GHz, 3x3, 26dBm
  - AR8035-A PHY	RGMII GbE with PoE+ IN
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM	NT5TU32M16FG
  - UART at J10		populated
  - 4 internal antenna plates (5 dbi, omni-directional)
  - 5 LEDs, 1 button (power, eth0, 2G, 5G, WPS) (reset)

**MAC addresses:**

  MAC addresses are labeled as ETH, 2.4G, and 5GHz
  Only one Vendor MAC address in flash

  eth0 ETH  *:fb art 0x0
  phy1 2.4G *:fc ---
  phy0 5GHz *:fd ---

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin at J10

**Installation:**

  2 ways to flash factory.bin from OEM:

  Method 1: Firmware upgrade page:

    OEM webpage at 192.168.1.1
    username and password "admin"
    Navigate to "Firmware Upgrade" page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    "192.168.1.1/index.htm"
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  If you have a serial cable, see Serial Failsafe instructions
  otherwise, uboot-env can be used to make uboot load the failsafe image

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs to 'vmlinux-art-ramdisk'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot
  execute tftpboot and bootm 0x81000000

  NOTE: TFTP is not reliable due to bugged bootloader
  set MTU to 600 and try many times
  if your TFTP server supports setting block size
  higher block size is better.

**Format of OEM firmware image:**

  The OEM software of EAP1750H is a heavily modified version
  of Openwrt Kamikaze. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-ar71xx-generic-eap1750h-uImage-lzma.bin
    openwrt-ar71xx-generic-eap1750h-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  Newer EnGenius software requires more checks but their script
  includes a way to skip them, otherwise the tar must include
  a text file with the version and md5sums in a deprecated format.

  The OEM upgrade script is at /etc/fwupgrade.sh.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied
  at the PHY side, using the at803x driver `phy-mode`.
  Therefore the PLL registers for GMAC0
  do not need the bits for delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

Serial console: 115200-8-N-1 on internal JP1 header.
Pinout:

---------- JP1
|5|4|3|2|1|
----------

Pin 1 is near the "H1" marking.
1 - RX
2 - n/c
3 - VCC (3.3V)
4 - GND
5 - TX

Installation:
There are two methods of installation:
- Using serial console [1] - requires some disassembly, 3.3V USB-Serial
  adapter, TFTP server,  and removing a single T10 screw,
  but with much less manual steps, and is generally recommended, being
  safer.
- Using stock firmware root shell exploit, SSH and TFTP [2]. Does not
  work on some rare versions of stock firmware. A more involved, and
  requires installing `mkenvimage` from u-boot-tools package if you
  choose to rebuild your own environment, but can be used without
  disassembly or removal from installation point, if you have the
  credentials.
  If for some reason, size of your sysupgrade image exceeds 13312kB,
  proceed with method [1]. For official images this is not likely to
  happen ever.

[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
   does not back-power the board, otherwise it will fail to boot.

1. Power-on the board. Then quickly connect serial converter to PC and
   hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
   you'll enter U-boot shell. Then skip to point 3.
   Connection parameters are 115200-8-N-1.

2. Allow the board to boot.  Press the reset button, so the board
   reboots into U-boot again and go back to point 1.

3. Set the "bootcmd" variable to disable the dual-boot feature of the
   system and ensure that uImage is loaded. This is critical step, and
   needs to be done only on initial installation.

   > setenv bootcmd "bootm 0x9f040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7025-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7025_fw1_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7025-squashfs-sysupgrade.bin

[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
   it boots, hold the reset button near Ethernet connectors for 5
   seconds.

1. Connect the device to the network. It will acquire address over DHCP,
   so either find its address using list of DHCP leases by looking for
   label MAC address, or try finding it by scanning for SSH port:

   $ nmap 10.42.0.0/24 -p22

   From now on, we assume your computer has address 10.42.0.1 and the device
   has address 10.42.0.254.

2. Set up a TFTP server on your computer. We assume that TFTP server
   root is at /srv/tftp.

3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
   frmware is pretty ancient and requires enabling HMAC-MD5.

   $ ssh 10.42.0.254 \
   -o UserKnownHostsFile=/dev/null \
   -o StrictHostKeyCheking=no \
   -o MACs=hmac-md5

   Login. User is "super", password is "sp-admin".
   Now execute a hidden command:

   Ruckus

   It is case-sensitive. Copy and paste the following string,
   including quotes. There will be no output on the console for that.

   ";/bin/sh;"

   Hit "enter". The AP will respond with:

   grrrr
   OK

   Now execute another hidden command:

   !v54!

   At "What's your chow?" prompt just hit "enter".
   Congratulations, you should now be dropped to Busybox shell with root
   permissions.

4. Optional, but highly recommended: backup the flash contents before
   installation. At your PC ensure the device can write the firmware
   over TFTP:

   $ sudo touch /srv/tftp/ruckus_zf7025_firmware{1,2}.bin
   $ sudo chmod 666 /srv/tftp/ruckus_zf7025_firmware{1,2}.bin

   Locate partitions for primary and secondary firmware image.
   NEVER blindly copy over MTD nodes, because MTD indices change
   depending on the currently active firmware, and all partitions are
   writable!

   # grep rcks_wlan /proc/mtd

   Copy over both images using TFTP, this will be useful in case you'd
   like to return to stock FW in future. Make sure to backup both, as
   OpenWrt uses bot firmwre partitions for storage!

   # tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7025_firmware1.bin -p 10.42.0.1
   # tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7025_firmware2.bin -p 10.42.0.1

   When the command finishes, copy over the dump to a safe place for
   storage.

   $ cp /srv/tftp/ruckus_zf7025_firmware{1,2}.bin ~/

5. Ensure the system is running from the BACKUP image, i.e. from
   rcks_wlan.bkup partition or "image 2". Otherwise the installation
   WILL fail, and you will need to access mtd0 device to write image
   which risks overwriting the bootloader, and so is not covered here
   and not supported.

   Switching to backup firmware can be achieved by executing a few
   consecutive reboots of the device, or by updating the stock firmware. The
   system will boot from the image it was not running from previously.
   Stock firmware available to update was conveniently dumped in point 4 :-)

6. Prepare U-boot environment image.
   Install u-boot-tools package. Alternatively, if you build your own
   images, OpenWrt provides mkenvimage in host staging directory as well.
   It is recommended to extract environment from the device, and modify
   it, rather then relying on defaults:

   $ sudo touch /srv/tftp/u-boot-env.bin
   $ sudo chmod 666 /srv/tftp/u-boot-env.bin

   On the device, find the MTD partition on which environment resides.
   Beware, it may change depending on currently active firmware image!

   # grep u-boot-env /proc/mtd

   Now, copy over the partition

   # tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1

   Store the stock environment in a safe place:

   $ cp /srv/tftp/u-boot-env.bin ~/

   Extract the values from the dump:

   $ strings u-boot-env.bin | tee u-boot-env.txt

   Now clean up the debris at the end of output, you should end up with
   each variable defined once. After that, set the bootcmd variable like
   this:

   bootcmd=bootm 0x9f040000

   You should end up with something like this:

bootcmd=bootm 0x9f040000
bootargs=console=ttyS0,115200 rootfstype=squashfs init=/sbin/init

   These are the defaults, you can use most likely just this as input to
   mkenvimage.

   Now, create environment image and copy it over to TFTP root:

   $ mkenvimage -s 0x40000 -b -o u-boot-env.bin u-boot-env.txt
   $ sudo cp u-boot-env.bin /srv/tftp

   This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
   TFTP root:

   $ sudo cp openwrt-ath79-generic-ruckus_zf7025-squashfs-sysupgrade.bin /srv/tftp

   Now load both to the device over TFTP:

   # tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
   # tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7025-squashfs-sysupgrade.bin -g 10.42.0.1

   Verify checksums of both images to ensure the transfer over TFTP
   was completed:

   # sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin

   And compare it against source images:

   $ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7025-squashfs-sysupgrade.bin

   Locate MTD partition of the primary image:

   # grep rcks_wlan.main /proc/mtd

   Now, write the images in place. Write U-boot environment last, so
   unit still can boot from backup image, should power failure occur during
   this. Replace MTD placeholders with real MTD nodes:

   # flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
   # flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>

   Finally, reboot the device. The device should directly boot into
   OpenWrt. Look for the characteristic power LED blinking pattern.

   # reboot -f

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Boot into OpenWrt initramfs as for initial installation. To do that
   without disassembly, you can write an initramfs image to the device
   using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Concatenate the firmware backups, if you took them during installation using method 2:

   $ cat ruckus_zf7025_fw1_backup.bin ruckus_zf7025_fw2_backup.bin > ruckus_zf7025_backup.bin

3. Write factory images downloaded from manufacturer website into
   fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
   before installation:

   # mtd write ruckus_zf7025_backup.bin /dev/mtd1

4. Reboot the system, it should load into factory firmware again.

Quirks and known issues:
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
- The 2.4 GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid   the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.

20581ee8b5 ath79: add support for TP-Link Deco S4
Add support for TP-Link Deco S4 wifi router

The label refers to the device as S4R and the TP-Link firmware
site calls it the Deco S4 v2. (There does not appear to be a v1)

Hardware (and FCC id) are identical to the Deco M4R v2 but the
flash layout is ordered differently and the OEM firmware encrypts
some config parameters (including the label mac address) in flash

In order to set the encrypted mac address, the wlan's caldata
node is removed from the DTS so the mac can be decrypted with
the help of the uencrypt tool and patched into the wlan fw
via hotplug

Specifications:
SoC: QCA9563-AL3A
RAM: Zentel A3R1GE40JBF
Wireless 2.4GHz: QCA9563-AL3A (main SoC)
Wireless 5GHz: QCA9886
Ethernet Switch: QCA8337N-AL3C
Flash: 16 MB SPI NOR

UART serial access (115200N1) on board via solder pads:
RX = TP1 pad
TX = TP2 pad
GND = C201 (pad nearest board edge)

The device's bootloader and web gui will only accept images that
were signed using TP-Link's RSA key, however a memory safety bug
in the bootloader can be leveraged to install openwrt without
accessing the serial console. See developer forum S4 support page
for link to a "firmware" file that starts a tftp client, or you
may generate one on your own like this:

5df1b33298 ath79: add support for Senao Watchguard AP100
FCC ID: U2M-CAP2100AG

WatchGuard AP100 is an indoor wireless access point with
1 Gb ethernet port, dual-band but single-radio wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EAP300 v2
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - AR9344 SOC          MIPS 74kc, 2.4 GHz AND 5 GHz WMAC, 2x2
  - AR8035-A EPHY       RGMII GbE with PoE+ IN
  - 25 MHz clock
  - 16 MB FLASH         mx25l12805d
  - 2x 64 MB RAM
  - UART console        J11, populated
  - GPIO watchdog       GPIO 16, 20 sec toggle
  - 2 antennas          5 dBi, internal omni-directional plates
  - 5 LEDs              power, eth0 link/data, 2G, 5G
  - 1 button            reset

**MAC addresses:**

  Label has no MAC
  Only one Vendor MAC address in flash at art 0x0

  eth0 ---- *:e5 art 0x0 -2
  phy0 ---- *:e5 art 0x0 -2

**Installation:**

  Method 1: OEM webpage

    use OEM webpage for firmware upgrade to upload factory.bin

  Method 2: root shell

    It may be necessary to use a Watchguard router to flash the image to the AP
    and / or to downgrade the software on the AP to access SSH
    For some Watchguard devices, serial console over UART is disabled.

  NOTE: DHCP is not enabled by default after flashing

**TFTP recovery:**

  reset button has no function at boot time
  only possible with modified uboot environment,
  (see commit message for Watchguard AP300)

**Return to OEM:**

  user should make backup of MTD partitions
  and write the backups back to mtd devices
  in order to revert to OEM reliably

  It may be possible to use sysupgrade
  with an OEM image as well...
  (not tested)

**OEM upgrade info:**

  The OEM upgrade script is at /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

**Note on eth0 PLL-data:**

  The default Ethernet Configuration register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For AR934x series, the PLL registers for eth0
  can be see in the DTSI as 0x2c.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x1805002c 1`.

  The clock delay required for RGMII can be applied
  at the PHY side, using the at803x driver `phy-mode`.
  Therefore the PLL registers for GMAC0
  do not need the bits for delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

**Note on WatchGuard Magic string:**

  The OEM upgrade script is a modified version of
  the generic Senao sysupgrade script
  which is used on EnGenius devices.

  On WatchGuard boards produced by Senao,
  images are verified using a md5sum checksum of
  the upgrade image concatenated with a magic string.
  this checksum is then appended to the end of the final image.

  This variable does not apply to all the senao devices
  so set to null string as default

146aaeafb7 ath79: add support for Senao WatchGuard AP300
FCC ID: Q6G-AP300

WatchGuard AP300 is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EAP1750
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - QCA9558 SOC		MIPS 74kc, 2.4 GHz WMAC, 3x3
  - QCA9880 WLAN	PCI card 168c:003c, 5 GHz, 3x3, 26dBm

  - 6 antennas		5 dBi, internal omni-directional plates
  - 5 LEDs		power, eth0 link/data, 2G, 5G
  - 1 button		reset

**MAC addresses:**

  MAC address labeled as ETH
  Only one Vendor MAC address in flash at art 0x0

  eth0 ETH  *:3c art 0x0
  phy1 ---- *:3d ---
  phy0 ---- *:3e ---

**Serial console access:**

  For this board, its not certain whether UART is possible
  it is likely that software is blocking console access

  the RX line on the board for UART is shorted to ground by resistor R176
  the resistors R175 and R176 are next to the UART RX pin at J10

  however console output is garbage even after this fix

**Installation:**

  Method 1: OEM webpage

    use OEM webpage for firmware upgrade to upload factory.bin

  Method 2: root shell access

    downgrade XTM firewall to v2.0.0.1
    downgrade AP300 firmware: v1.0.1
    remove / unpair AP from controller
    perform factory reset with reset button
    connect ethernet to a computer
    login to OEM webpage with default address / pass: wgwap
    enable SSHD in OEM webpage settings
    access root shell with SSH as user 'root'
    modify uboot environment to automatically try TFTP at boot time
    (see command below)

    rename initramfs-kernel.bin to test.bin
    load test.bin over TFTP (see TFTP recovery)
    (optionally backup all mtdblocks to have flash backup)
    perform a sysupgrade with sysupgrade.bin

  NOTE: DHCP is not enabled by default after flashing

**TFTP recovery:**

  server ip: 192.168.1.101

  reset button seems to do nothing at boot time...
  only possible with modified uboot environment,
  running this command in the root shell:

  fw_setenv bootcmd 'if ping 192.168.1.101; then tftp 0x82000000 test.bin && bootm 0x82000000; else bootm 0x9f0a0000; fi'

  and verify that it is correct with

  fw_printenv

  then, before boot, the device will attempt TFTP from 192.168.1.101
  looking for file 'test.bin'

  to return uboot environment to normal:

  fw_setenv bootcmd 'bootm 0x9f0a0000'

**Return to OEM:**

  user should make backup of MTD partitions
  and write the backups back to mtd devices
  in order to revert to OEM
  (see installation method 2)

  It may be possible to use sysupgrade
  with an OEM image as well...
  (not tested)

**OEM upgrade info:**

  The OEM upgrade script is at /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

**Note on eth0 PLL-data:**

  The default Ethernet Configuration register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied
  at the PHY side, using the at803x driver `phy-mode`.
  Therefore the PLL registers for GMAC0
  do not need the bits for delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

**Note on WatchGuard Magic string:**

  The OEM upgrade script is a modified version of
  the generic Senao sysupgrade script
  which is used on EnGenius devices.

  On WatchGuard boards produced by Senao,
  images are verified using a md5sum checksum of
  the upgrade image concatenated with a magic string.
  this checksum is then appended to the end of the final image.

  This variable does not apply to all the senao devices
  so set to null string as default

f1d112ee5a ath79: support Ruckus ZoneFlex 7321
Ruckus ZoneFlex 7321 is a dual-band, single radio 802.11n 2x2 MIMO enterprise
access point. It is very similar to its bigger brother, ZoneFlex 7372.

Hardware highligts:
- CPU: Atheros AR9342 SoC at 533 MHz
- RAM: 64MB DDR2
- Flash: 32MB SPI-NOR
- Wi-Fi: AR9342 built-in dual-band 2x2 MIMO radio
- Ethernet: single Gigabit Ethernet port through AR8035 gigabit PHY
- PoE: input through Gigabit port
- Standalone 12V/1A power input
- USB: optional single USB 2.0 host port on the 7321-U variant.

Serial console: 115200-8-N-1 on internal H1 header.
Pinout:

H1 ----------
   |1|x3|4|5|
   ----------

Pin 1 is near the "H1" marking.
1 - RX
x - no pin
3 - VCC (3.3V)
4 - GND
5 - TX

JTAG: Connector H5, unpopulated, similar to MIPS eJTAG, standard,
but without the key in pin 12 and not every pin routed:

------- H5
|1 |2 |
-------
|3 |4 |
-------
|5 |6 |

|7 |8 |
-------
|9 |10|

3 - TDI
5 - TDO
7 - TMS
9 - TCK
2,4,6,8,10 - GND
14 - Vref
1,11,12,13 - Not connected

Installation:
There are two methods of installation:
- Using serial console [1] - requires some disassembly, 3.3V USB-Serial
  adapter, TFTP server,  and removing a single T10 screw,
  but with much less manual steps, and is generally recommended, being
  safer.
- Using stock firmware root shell exploit, SSH and TFTP [2]. Does not
  work on some rare versions of stock firmware. A more involved, and
  requires installing `mkenvimage` from u-boot-tools package if you
  choose to rebuild your own environment, but can be used without
  disassembly or removal from installation point, if you have the
  credentials.
  If for some reason, size of your sysupgrade image exceeds 13312kB,
  proceed with method [1]. For official images this is not likely to
  happen ever.

[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
   does not back-power the board, otherwise it will fail to boot.

1. Power-on the board. Then quickly connect serial converter to PC and
   hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
   you'll enter U-boot shell. Then skip to point 3.
   Connection parameters are 115200-8-N-1.

2. Allow the board to boot.  Press the reset button, so the board
   reboots into U-boot again and go back to point 1.

3. Set the "bootcmd" variable to disable the dual-boot feature of the
   system and ensure that uImage is loaded. This is critical step, and
   needs to be done only on initial installation.

   > setenv bootcmd "bootm 0x9f040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7321-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7321_fw1_backup.bin
   $ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7321_fw2_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin

[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
   it boots, hold the reset button near Ethernet connectors for 5
   seconds.

1. Connect the device to the network. It will acquire address over DHCP,
   so either find its address using list of DHCP leases by looking for
   label MAC address, or try finding it by scanning for SSH port:

   $ nmap 10.42.0.0/24 -p22

   From now on, we assume your computer has address 10.42.0.1 and the device
   has address 10.42.0.254.

2. Set up a TFTP server on your computer. We assume that TFTP server
   root is at /srv/tftp.

3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
   frmware is pretty ancient and requires enabling HMAC-MD5.

   $ ssh 10.42.0.254 \
   -o UserKnownHostsFile=/dev/null \
   -o StrictHostKeyCheking=no \
   -o MACs=hmac-md5

   Login. User is "super", password is "sp-admin".
   Now execute a hidden command:

   Ruckus

   It is case-sensitive. Copy and paste the following string,
   including quotes. There will be no output on the console for that.

   ";/bin/sh;"

   Hit "enter". The AP will respond with:

   grrrr
   OK

   Now execute another hidden command:

   !v54!

   At "What's your chow?" prompt just hit "enter".
   Congratulations, you should now be dropped to Busybox shell with root
   permissions.

4. Optional, but highly recommended: backup the flash contents before
   installation. At your PC ensure the device can write the firmware
   over TFTP:

   $ sudo touch /srv/tftp/ruckus_zf7321_firmware{1,2}.bin
   $ sudo chmod 666 /srv/tftp/ruckus_zf7321_firmware{1,2}.bin

   Locate partitions for primary and secondary firmware image.
   NEVER blindly copy over MTD nodes, because MTD indices change
   depending on the currently active firmware, and all partitions are
   writable!

   # grep rcks_wlan /proc/mtd

   Copy over both images using TFTP, this will be useful in case you'd
   like to return to stock FW in future. Make sure to backup both, as
   OpenWrt uses bot firmwre partitions for storage!

   # tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7321_firmware1.bin -p 10.42.0.1
   # tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7321_firmware2.bin -p 10.42.0.1

   When the command finishes, copy over the dump to a safe place for
   storage.

   $ cp /srv/tftp/ruckus_zf7321_firmware{1,2}.bin ~/

5. Ensure the system is running from the BACKUP image, i.e. from
   rcks_wlan.bkup partition or "image 2". Otherwise the installation
   WILL fail, and you will need to access mtd0 device to write image
   which risks overwriting the bootloader, and so is not covered here
   and not supported.

   Switching to backup firmware can be achieved by executing a few
   consecutive reboots of the device, or by updating the stock firmware. The
   system will boot from the image it was not running from previously.
   Stock firmware available to update was conveniently dumped in point 4 :-)

6. Prepare U-boot environment image.
   Install u-boot-tools package. Alternatively, if you build your own
   images, OpenWrt provides mkenvimage in host staging directory as well.
   It is recommended to extract environment from the device, and modify
   it, rather then relying on defaults:

   $ sudo touch /srv/tftp/u-boot-env.bin
   $ sudo chmod 666 /srv/tftp/u-boot-env.bin

   On the device, find the MTD partition on which environment resides.
   Beware, it may change depending on currently active firmware image!

   # grep u-boot-env /proc/mtd

   Now, copy over the partition

   # tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1

   Store the stock environment in a safe place:

   $ cp /srv/tftp/u-boot-env.bin ~/

   Extract the values from the dump:

   $ strings u-boot-env.bin | tee u-boot-env.txt

   Now clean up the debris at the end of output, you should end up with
   each variable defined once. After that, set the bootcmd variable like
   this:

   bootcmd=bootm 0x9f040000

   You should end up with something like this:

bootcmd=bootm 0x9f040000
bootargs=console=ttyS0,115200 rootfstype=squashfs init=/sbin/init
baudrate=115200
ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee
mtdparts=mtdparts=ar7100-nor0:256k(u-boot),13312k(rcks_wlan.main),2048k(datafs),256k(u-boot-env),512k(Board Data),13312k(rcks_wlan.bkup)
mtdids=nor0=ar7100-nor0
bootdelay=2
ethact=eth0
filesize=78a000
fileaddr=81000000
partition=nor0,0
mtddevnum=0
mtddevname=u-boot
ipaddr=10.0.0.1
serverip=10.0.0.5
stdin=serial
stdout=serial
stderr=serial

   These are the defaults, you can use most likely just this as input to
   mkenvimage.

   Now, create environment image and copy it over to TFTP root:

   $ mkenvimage -s 0x40000 -b -o u-boot-env.bin u-boot-env.txt
   $ sudo cp u-boot-env.bin /srv/tftp

   This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
   TFTP root:

   $ sudo cp openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin /srv/tftp

   Now load both to the device over TFTP:

   # tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
   # tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin -g 10.42.0.1

   Vverify checksums of both images to ensure the transfer over TFTP
   was completed:

   # sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin

   And compare it against source images:

   $ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin

   Locate MTD partition of the primary image:

   # grep rcks_wlan.main /proc/mtd

   Now, write the images in place. Write U-boot environment last, so
   unit still can boot from backup image, should power failure occur during
   this. Replace MTD placeholders with real MTD nodes:

   # flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
   # flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>

   Finally, reboot the device. The device should directly boot into
   OpenWrt. Look for the characteristic power LED blinking pattern.

   # reboot -f

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Boot into OpenWrt initramfs as for initial installation. To do that
   without disassembly, you can write an initramfs image to the device
   using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Write factory images downloaded from manufacturer website into
   fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
   before installation:
   mtd write ruckus_zf7321_fw1_backup.bin /dev/mtd1
   mtd write ruckus_zf7321_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.

Quirks and known issues:
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
- The 5GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid   the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- U-boot disables JTAG when starting. To re-enable it, you need to
  execute the following command before booting:
  mw.l 1804006c 40
  And also you need to disable the reset button in device tree if you
  intend to debug Linux, because reset button on GPIO0 shares the TCK
  pin.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.

   > setenv bootcmd "bootm 0x9f040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7372-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7372_fw1_backup.bin
   $ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7372_fw2_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin

[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
   it boots, hold the reset button near Ethernet connectors for 5
   seconds.

1. Connect the device to the network. It will acquire address over DHCP,
   so either find its address using list of DHCP leases by looking for
   label MAC address, or try finding it by scanning for SSH port:

   $ nmap 10.42.0.0/24 -p22

   From now on, we assume your computer has address 10.42.0.1 and the device
   has address 10.42.0.254.

2. Set up a TFTP server on your computer. We assume that TFTP server
   root is at /srv/tftp.

3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
   frmware is pretty ancient and requires enabling HMAC-MD5.

   $ ssh 10.42.0.254 \
   -o UserKnownHostsFile=/dev/null \
   -o StrictHostKeyCheking=no \
   -o MACs=hmac-md5

   Login. User is "super", password is "sp-admin".
   Now execute a hidden command:

   Ruckus

   It is case-sensitive. Copy and paste the following string,
   including quotes. There will be no output on the console for that.

   ";/bin/sh;"

   Hit "enter". The AP will respond with:

   grrrr
   OK

   Now execute another hidden command:

   !v54!

   At "What's your chow?" prompt just hit "enter".
   Congratulations, you should now be dropped to Busybox shell with root
   permissions.

4. Optional, but highly recommended: backup the flash contents before
   installation. At your PC ensure the device can write the firmware
   over TFTP:

   $ sudo touch /srv/tftp/ruckus_zf7372_firmware{1,2}.bin
   $ sudo chmod 666 /srv/tftp/ruckus_zf7372_firmware{1,2}.bin

   Locate partitions for primary and secondary firmware image.
   NEVER blindly copy over MTD nodes, because MTD indices change
   depending on the currently active firmware, and all partitions are
   writable!

   # grep rcks_wlan /proc/mtd

   Copy over both images using TFTP, this will be useful in case you'd
   like to return to stock FW in future. Make sure to backup both, as
   OpenWrt uses bot firmwre partitions for storage!

   # tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7372_firmware1.bin -p 10.42.0.1
   # tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7372_firmware2.bin -p 10.42.0.1

   When the command finishes, copy over the dump to a safe place for
   storage.

   $ cp /srv/tftp/ruckus_zf7372_firmware{1,2}.bin ~/

5. Ensure the system is running from the BACKUP image, i.e. from
   rcks_wlan.bkup partition or "image 2". Otherwise the installation
   WILL fail, and you will need to access mtd0 device to write image
   which risks overwriting the bootloader, and so is not covered here
   and not supported.

   Switching to backup firmware can be achieved by executing a few
   consecutive reboots of the device, or by updating the stock firmware. The
   system will boot from the image it was not running from previously.
   Stock firmware available to update was conveniently dumped in point 4 :-)

6. Prepare U-boot environment image.
   Install u-boot-tools package. Alternatively, if you build your own
   images, OpenWrt provides mkenvimage in host staging directory as well.
   It is recommended to extract environment from the device, and modify
   it, rather then relying on defaults:

   $ sudo touch /srv/tftp/u-boot-env.bin
   $ sudo chmod 666 /srv/tftp/u-boot-env.bin

   On the device, find the MTD partition on which environment resides.
   Beware, it may change depending on currently active firmware image!

   # grep u-boot-env /proc/mtd

   Now, copy over the partition

   # tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1

   Store the stock environment in a safe place:

   $ cp /srv/tftp/u-boot-env.bin ~/

   Extract the values from the dump:

   $ strings u-boot-env.bin | tee u-boot-env.txt

   Now clean up the debris at the end of output, you should end up with
   each variable defined once. After that, set the bootcmd variable like
   this:

   bootcmd=bootm 0x9f040000

   You should end up with something like this:

bootcmd=bootm 0x9f040000

   $ sudo cp u-boot-env.bin /srv/tftp

   This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
   TFTP root:

   $ sudo cp openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin /srv/tftp

   Now load both to the device over TFTP:

   # tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
   # tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin -g 10.42.0.1

   Verify checksums of both images to ensure the transfer over TFTP
   was completed:

   # sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin

   And compare it against source images:

   $ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin

   Locate MTD partition of the primary image:

   # grep rcks_wlan.main /proc/mtd

   Now, write the images in place. Write U-boot environment last, so
   unit still can boot from backup image, should power failure occur during
   this. Replace MTD placeholders with real MTD nodes:

   # flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
   # flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>

   Finally, reboot the device. The device should directly boot into
   OpenWrt. Look for the characteristic power LED blinking pattern.

   # reboot -f

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Boot into OpenWrt initramfs as for initial installation. To do that
   without disassembly, you can write an initramfs image to the device
   using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Write factory images downloaded from manufacturer website into
   fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
   before installation:
   mtd write ruckus_zf7372_fw1_backup.bin /dev/mtd1
   mtd write ruckus_zf7372_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.

Quirks and known issues:
- This is first device in ath79 target to support link state reporting
  on FE port attached trough the built-in switch.
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
  The 5GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid   the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- U-boot disables JTAG when starting. To re-enable it, you need to
  execute the following command before booting:
  mw.l 1804006c 40
  And also you need to disable the reset button in device tree if you
  intend to debug Linux, because reset button on GPIO0 shares the TCK
  pin.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.
  Source: https://alephsecurity.com/vulns/aleph-2019014
- Stock firmware has beamforming functionality, known as BeamFlex,
  using active multi-segment antennas on both bands - controlled by
  RF analog switches, driven by a pair of 74LV164 shift registers.
  Shift registers used for each radio are connected to GPIO14 (clock)
  and GPIO15 of the respective chip.
  They are mapped as generic GPIOs in OpenWrt - in stock firmware,
  they were most likely handled directly by radio firmware,
  given the real-time nature of their control.
  Lack of this support in OpenWrt causes the antennas to behave as
  ordinary omnidirectional antennas, and does not affect throughput in
  normal conditions, but GPIOs are available to tinker with nonetheless.

0dc5821489 ath79: add support for Sophos AP15
The Sophos AP15 seems to be very close to Sophos AP55/AP100.

Based on:
commit 6f1efb2898 ("ath79: add support for Sophos AP100/AP55 family")
author    Andrew Powers-Holmes <andrew@omnom.net>
          Fri, 3 Sep 2021 15:53:57 +0200 (23:53 +1000)
committer Hauke Mehrtens <hauke@hauke-m.de>
          Sat, 16 Apr 2022 16:59:29 +0200 (16:59 +0200)

Unique to AP15:
 - Green and yellow LED
 - 2T2R 2.4GHz 802.11b/g/n via SoC WMAC
 - No buttons
 - No piezo beeper
 - No 5.8GHz

Flashing instructions:
 - Derived from UART method described in referenced commit, methods
   described there should work too.
 - Set up a TFTP server; IP address has to be 192.168.99.8/24
 - Copy the firmware (initramfs-kernel) to your TFTP server directory
   renaming it to e.g. boot.bin
 - Open AP's enclosure and locate UART header (there is a video online)
 - Terminal connection parameters are 115200 8/N/1
 - Connect TFTP server and AP via ethernet
 - Power up AP and cancel autoboot when prompted
 - Prompt shows 'ath> '
 - Commands used to boot:
    ath> tftpboot 0x81000000 boot.bin
    ath> bootm 0x81000000
 - Device should boot OpenWRT
 - IP address after boot is 192.168.1.1/24
 - Connect to device via browser
 - Permanently flash using the web ui (flashing sysupgrade image)
 - (BTW: the AP55 images seem to work too, only LEDs are not working)

Testing done:
 - To be honest: Currently not so much testing done.
 - Flashed onto two devices
 - Devices are booting
 - MAC addresses are correct
 - LEDs are working
 - Scanning for WLANs is working

Big thanks to all the people working on this great project!

Important notes:

the PLC firmware has to be provided and copied manually onto the
device! The PLC here has no dedicated flash, thus the firmware file
has to be uploaded to the PLC controller at every system start
the PLC functionality is managed by the script /etc/init.d/plc_basic,
a very basic script based on the the one from Netadair (netadair dot de)
Installation:

Additional notes:

the pairing buttons have to have pressed for at least half a second,
it doesn't matter on which plc device (master or slave) first
it is possible to pair the devices without the button-pairing requirement
simply by pressing reset on the slave device. This will default to the
firmware settings, which is also how the plc_basic script is setting up
the master device, i.e. configuring it to firmware defaults
the PL-E56P slave PLC has its dedicated 4MByte SPI, thus it is capable
to store all firmware currently available. Note that some other
slave devices are not guarantied to have the capacity for the newer
~1MByte firmware blobs!
To have a good overlook about the slave device, here are its specs:
same QCA7500 PLC controller, same w631gg6kb-15 128MB RAM,
25L3233F 4MB SPI-NOR and an AR8035-A 1000M-Transceiver
